Steel in the News

Older buildings with steel frames, such as the Wellington, New Zealand building shown in the above photo, remain standing after a magnitude 4.5 earthquake hit the city just over two months ago. Research on the performance of steel structures in the New Zealand events as well as observations on the devastation in Japan will be discussed in AISC’s free webinar on May 12 at 8:00 a.m. EDT.
First in September, and then again in February, large earthquakes struck New Zealand killing 200 and causing more than $20 billion in damage. On March 11 Japan was rocked by a magnitude 8.9 earthquake and a 30-foot tsunami that claimed hundreds of lives, evacuated thousands from their homes, and damaged the Fukushima nuclear plant. Seismic research has begun on the structural damage that occurred in these two disastrous events and you can learn about it at this year’s NASCC: The Steel Conference on Thursday, May 12 at 8:00 a.m. EDT. Or, if you’re unable to attend the conference in person, AISC will stream the session live over the Internet for free at www.aisc.org/nascclive.
Alistair Fussell, manager of Steel Construction New Zealand (SCNZ) will provide an overview of the events in New Zealand with a special emphasis on the performance of steel structures. Included will be a look at the performance of pure Eccentrically Braced Frames (EBFs), combination EBF/Moment Resisting Frames (MRFs), and Concentrically Braced Frames (CBFs). Finally, he’ll provide some details on seismic research currently underway in New Zealand.
Gilberto Mosqueda of the University of Buffalo, who traveled to Japan after the earthquake, will report on what he saw there. His report will consist of preliminary observations of structural seismic and tsunami damage. Structural damage reports are still preliminary, but this session will report on what is currently known.
